South Anna River
The South Anna River is a principal tributary of the Pamunkey River, about 102 miles (164 km) long, in central Virginia in the United States. Via the Pamunkey and York rivers, it is part of the watershed of Chesapeake Bay.
The South Anna River rises near Gordonsville in southwestern Orange County and flows generally southeastwardly and eastwardly through Louisa and Hanover counties. It joins the North Anna River to form the Pamunkey River about 5 miles (8.0 km) northeast of Ashland.
Near its mouth the river collects the Newfound River.
